PARAFFINING APPARATUS.

'Lpplicatmn filed July 14, 1921. Serial No. 484,604.

To all whom it may concern:

Be it known thatI, IRvmc STANLEY, a citizen of the United States, and aresident otthe borough of Manhattan, in the city, county, and State ofNew York, have invented certain new and useful Improvements inParaifining Apparatus, of which the following is a specification.

This invention relates to apparatus for impregnating articles made ofpaper with paraiiine to make the same impervious to moisture andliquids, and relates particularly to paraiiining of receptacles orcontainersmade of paper, and it is the primary object of the inventionto provide apparatus of this character for treating articlessuccessively in a continuous manner and provide apparatus for thispurpose whichis simple in structure, and eflicient in use.

In the treatment of paper articles to be paraflined it is essentialforthe efficient im-' .pregnating of the material by the parafline I thatthe parafiine be in'a highly liquid state,

and after the article has been subjected to the parafiine bath that thearticle be quickly chilled in I order to cause the parafiine t0 eedf 1evenly coat the article, and it is a further object of the invention toprovide improved means for subjecting the article to the parafline whilein a heated and dissolved structed and arranged with means to cause thearticles carried by the conveyer to be mmersed in the parafline withoutimmersing the conveyor with the consequent interference in the efficientoperation of the ap-.

paratus and necessitating the constant cleaning of the same. 7'

t is a further object of the invention to provide the conveyer'withimproved arti- V cle carryingmeans arranged to automatically pick up anarticle from a support and transport the same through the parafliningchamber or receptacle and refrigerator, and to release the article fromthe conveyor as it is delivered from the refrigerator.

.It is a further object of the invention to provide apparatus of thischaracter to be used in connection with apparatus for making paperreceptacles or containers, and to provide means to deliver articles fromsaid apparatus to the article carriers of the .conveyer.

Other objects and advantages will hereinafter appear I In the drawingsaccompanying and forming a part of thisspecification Figure 1 is aperspective view of an apparatus illustrating 'an' embodiment of myinvention;.

Similar characters of reference designate like parts throughout thedifferent views of.

the drawings.

In the embodiment of my invention shown in the drawings .the operativemechanism is mounted upon -a framework consisting of a Figure 7 is adetail view in plan of a por-- articles by pair of parallel angle irons9 rigidly connected by cross bars and Supported by legs or standards 10.i

A tank or receptacle 11 having an open= ing in the top with a removablecover 12 and to contain parafline, as shown at 13, is mounted upon theconnecting cross bars of the framework the paraffine being dissolved andmaintained in a dissolved and liquid state by the application of heat,shown as a coil or pipe 14 in the receptacle connected to a series ofheat supply such as steam.

-A' refrigerator is mounted upon the cross bars of the framework injuxtaposed relation to the parafline chamber and comprises a chamber ortank 15' having an opening in the top with a removable cover 16, saidchamber containing a ice 17, and a cooling coil 18 extendinglongitudinally thereof above the refrigerant.

refrigerant such as mounted upon the framework below the upper stretchof the conveyer and at the entering end of the parafline chamber 11.

As stated the apparatus is to be used in connection with apparatus. formaking the article 33 and is delivered from such apparatus to the shelf38. For this purpose a second conveyer 39 is provided a belt passingover rollers 40, 41, and actuconsisting of The para'ffine chamber hasalined openings 'ated by rotating the roller 40 from a suit- 19, 20 1nthe opposite end walls, and the refrigerant chamber also has aline'dopenings 21, 22 in the opposite end walls in line with the openings inthe parafline chamberand the opening through the, coil 18. In thestructure of the coil shownin Figurei2 the Wall of the,coil isperforated, as shown at 23, the coil being connected to a blower,indicated in a general way at 24, to discharge a plurality of sprays ofjets of air from the coil in a direction toward the interior there'- Thearticle or articles to be paralhned are transported to the paraifinechamber and the refrigerator by a conveyer comprising a pair of sprocketchains 25 passing around a pair of sprocket wheels 26 fixed in spacedrelation on a shaft 27 and sprocket wheels 28 fixed in spaced relationon a shaft 29 and guided below the paraflining chamber and Y sprocketwheels 30 and 31.

32, and by means of which bars rangement of the-sprocket wheels thechains are maintained in parallel and spaced relation. The-mounting ofthe sprocket wheel shafts 27 and 29 are so arran ed that the upperstretch of-the conveyer Wlll pass through the openings 19, 20 of her andthe openings erator.

The apparatus is adapted to parafiine articles of different shape andcharacter and in the present instance is arranged to treat 21, 22 of therefrigreceptacles of truncated conical form having a closure in the endof greatest diameter as shown at 33. To support and transport theconveyer the conveyeris arranged with a series of successive articlecarriers, each of said carriers consisting of a member 34 fixed to thetransverse bars 32 substantially midway between the ends thereof and theconveyer chains with the end 35 bent'at right angles to extend inwardlythe paraffining cham- The conveyer 25 is intermittently actuated andduring the periods of rest the article is delivered by the plunger orram 46 from the conveyer 39 to the article support 38 and to permit ofthe positioning of the article on the support the arm 36 of the articlecarrier is moved to the position shown at 36- 111 Figure 2 by a finger47 carried by the ram engaging a projection 48 (Figures Guides Thearticles 6 and 7 on the arm, rocking said arm Y against the tension ofthe spring 37 As the ram is returned to initial position the finger 47is released from the arm projection 48 when said arm will be moved bythe tension of the spring 37 to engage the end of the receptacle on thesupport 38 and position said receptacle with relation to the supportingfingers of the arm 35 of the carrier.

The travel of the conveyer through the parafiine chamber 11 is guided inits move-v ment to cause the articles being transported by the conveyercarriers to be entirely immersed in the paraffine without immersing theconveyer chains therein. For this purpose a pair of guide rollers 49 aremounted within the parafiine chamberover which the conveyer chains pass,a second pair of guide rollers 50 being rotatably supported injuxta-posed relation to the rollers 49 and under which the conveyerchains pass, the conveyer chains passing from said latter rollers undera pair ofguide rollers 51 supported in spaced relation to the rollers5.0

and to rotate on axes parallel therewith, the

chains passing from said latter rollers over guide rollers 52. As willbe clearly observedfrom Figure 2 by this arrangement of the guiderollers 49, 50, 51 and 52 the articles carried by the conveyer iii itstravel through the parafline chamber will cause the articles to beimmersed in the parafiiney- As the conveyer passes from the rollers 52the receptacles will be in an inclined p0 sition thereby permitting anyof parafiine contained therein todrain from the receptacle. It will benoted that in the passage of the conveyer through the parafiine chamherthat the conveyer will not be immersed a gui e 53 rocking the arm 36 andreleasing the article therefrom, such article dropping onto a chute 54and being able receiver R Figure 5.

The conveyer is operated intermittently deliveredto a suitfrom asuitable source of power and is shown as being actuated by pawl andratchet mechanism consisting of a ratchet wheel 55 fixed to shaft 27 ofthe sprocket wheels 26 and actuated by a pawl 56 pivotally carried by anarm 57 hung on the shaft 27. The arm is oscillated or actuated by a rod58 operatively connected to a cam 59 on a drive shaft 60 andconstituting a part of the apparatus for making the receptacles.

In the operation 01E the apparatus the articles are delivered from thereceptacle making apparatus to the, conveyer '39 as shown in dottedlines at 60in Figure '2. The articles are carried by the conveyer untilthey are arrested by the stop 45. During a period of rest of thearticleconveyor 25 the articlesare delivered from the conveyer 39 to thesupport 38 b the plunger or ram 46, the plunger in its elivery movementcausing the finger 47 to engage the projection 48 of the arm 36 movingthe same to the position shown at 36 in Figure v2, such movement of saidarm being previous to the delivery of the article to the sup-' port 38.The plunger immediately recedes from its feeding position therebywithdrawing the finger 47 from 'the arm projection 48 causing said armto move to position with the fingers thereof to engage the end of thereceptacle and causing said arm to position the receptacle relative tothe supporting fingers of the arm 35. An intermittent movement is thenimparted to the conveyer positioning a successive carrier with relationto the support 38 whenithe operation of de- The articles the parafliuein the receptacle; and a re livering a further article 39 is r'epeated.
